BSBI Welsh Bulletin No. 102 July 2018 3 Welsh Officer’s Update PAUL R. GREEN, email: [email protected] It is now 7 months (I only managed 9 months, see last paragraph) since I have been back as the BSBI Welsh Officer. On my days off, I do like to try and go out recording to help out with Atlas 2020. I always look at the Distribution Database (Ddb) before I head out, to see what species haven’t been recorded since 1999 for the hectad I’m going to visit. Normally, it is the rarer species, or species that are harder to identify that haven’t been recorded. Occasionally, there can be a common species which needs to be refound. In one instance, it was Lathyrus pratensis (Meadow Vetchling)…it was fun to think that a species, I expect to see nearly every time I am out recording, still needed to be updated to post 2000 for a hectad. Other species can be much more of a challenge to find! One of these was Prunus cerasus (Dwarf Cherry) (see image 2, page 2), with many hectads still needing a post 2000 record in Wales. After I had realised this, each time I went out and did some recording in late April, I always saw Dwarf Cherry in a hedgerow, partly because it was in full flower. It is a small tree that is extremely easy to over-look after the flowering period. Despite the spring being wet and cold much of the time, and the flowering season being a good 3 weeks late or even more, the three early meetings I lead had exceptionally good weather. On the coast at Freshwater West on 25th March, it was more like a treasure hunt trying to find any plant flowering. A month later, on the Viola workshop at Port-Eynon, it felt that spring had truly arrived, as it was a warm sunny day and many species were flowering. Only 4 species of Violet could be found. Viola odorata (Sweet Violet) had actually finished flowering, while the other three species seen were just coming into their best. The third walk was at Mwnt on the Cardiganshire coast on 3rd May. The flowering season was still late and many species I would have expect to be in flower, had not yet started. There were many uncommon species, such as Moenchia erecta (Upright Chickweed) and Sagina subulata (Heath Pearlwort) (see front cover image) on the steep rocky slopes, where both were abundant and in full flower. On the 17th May, I ran a willow workshop at Llanelli Wetland Centre, where 17 BSBI members joined me from as far away as Devon and Oxfordshire. The morning was spent looking at specimens of willows I had gathered and, in the afternoon, a walk was taken around the reserve to look at the many willow species recorded from the site. For personal reasons I decided to step down as Welsh Officer in mid-June. Not a decision I took lightly! 4 BSBI Welsh Bulletin No. 102 July 2018 Fumaria reuteri Boiss., Martin’s Ramping- fumitory, new to Wales TIM RICH, 57 Aberdulais Road, Cardiff CF14 2PH FAITH WILLIAMS, 1 Ffynon Ffigys Cottages, Gwaelod y Garth CF15 9JG On 13 January 2018, FW posted a Fumaria picture taken at Morganstown allotments, Cardiff (v.c. 41) on the ‘Wild flowers of Britain and Ireland’ Facebook page. Noting the deep pink flowers with nearly entire sepals, TR suspected it might be F. reuteri, which would be new to Wales. On 17 January 2018, FW showed TR the plants and he was able to confirm that they are indeed F. reuteri. There were a few plants along a communal path. Fumaria reuteri is now being found widely in Britain in ruderal habitats, probably due to the enhanced identification guidance in the BSBI Fumitory Handbook by Rose Murphy (2009). Key field features are the large 11-13 mm long, deep pink flowers with nearly entire sepals; such plants should be collected for verification as F. reuteri could occur elsewhere in Wales. The strongly 3-lobed stigma is a good confirmatory character under the microscope. Botanical comings and goings on a Pembrokeshire farm, 1999 – 2018 M.D. SUTTON, www.wyndrushwild.co.uk Almost 20 years ago, I was a Phase II Grassland surveyor for CCW in Pembrokeshire. Together with colleague Dan Guest, we spent three June days surveying a series of fields around Wyndrush Farm, near Redberth in the south of the county. Two things stood out for me at the time. This wasn’t the usual grassland site - a slope too steep to plough, or a damp field at the far end of the holding – the whole farm was almost unscathed. It was positively leaping with insects and birds as a result. The owner made an impression on me too. Once the local blacksmith, he was only days away from dying and, as I stood with him and his wife in his spartan kitchen, he was most concerned about what was going to happen to his cows. I was later told that he never bought a bag of fertiliser in his life, and he had clearly farmed traditionally – making hay, maintaining hedges, letting the hunt run over his ‘moors’. Our 1999 NVC survey concluded that ‘Wyndrush Pastures’ was ‘of at least moderate to high conservation value for its fairly extensive and intergrading BSBI Welsh Bulletin No. 102 July 2018 5 mixtures of dry neutral grassland (MG5a), rush Juncus and Purple Moor-grass Molinia pasture (M23a, M24 and M25), and tall herb fen (M27 and M28)’. The somewhat under-managed stands of MG5a in the central enclosures were considered of particular interest, together with the little modified patchwork of M23a and M24b/c in the lower field to the north of these. No particularly rare plants were found – Petty Whin (Genista anglica), Dyer’s Greenweed (G. tinctoria) and Southern Marsh-orchid (Dactylorhiza praetermissa) were the most significant finds. Creeping Willow (Salix repens), Whorled Caraway (Carum verticillatum) and Saw-wort (Serratula tinctoria) were noted in the Molinia pasture, but the Wavy St. John’s-wort (Hypericum undulatum) and Pale Sedge (Carex pallescens) were overlooked. A few clumps of Diffuse Rush (Juncus x diffusus) were found in tall marshy grassland, where they persist to this day. Over the next few years, the site was bought by a farmer known locally as ‘Green-grass’, notified as a SSSI by an organisation still prepared to act quickly when necessary, then given to me to ‘manage’ as a newly appointed Conservation Officer. How I eventually came to own (or rather, be owned by) 87 acres in 2006 and start managing for real is another tale. From a botanical perspective, the most significant occurrence during the tenure of ‘Green-grass’ was a brief-period of heavy grazing which churned up the top fields, and a somewhat insensitive approach to fencing which cleared a swathe of young trees and caused some rutting of wet ground. The latter brought to light a seed- bank of Three-lobed Crowfoot (Ranunculus tripartitus), at locations where historical access routes were apparent – the old Tenby road in horse-drawn days, a gap in the boundary bank which may have been used by the hunt, and an old gateway between fields. Up to 20 plants flowered for the first year or two, but subsequent cattle-grazing proved insufficient to maintain the plant above ground, and ten years later it (hopefully) returned to the seed-bank once more. My first years as a farmer went by in a frenzy of activity – I was still with CCW, so all spare time was taken with building, cattle management, beekeeping and hay-making amongst other things.
